The case is altered, however, when a man speaks of his personal memory. It must then assume all the deficiencies which belong to other mental powers. We lawyers, especially, hear frequently from witnesses: “My memory is too weak to answer this question,” “Since receiving the wound in question my memory has failed,” “I am already too old, my memory is leaving me,” etc. In each of these cases, however, it is not the memory that is at fault. As a matter of fact the witness ought to have said “I am too stupid to answer this question,” “Since the wound in question, my intellectual powers have failed,” “I am already old, I am growing silly,” etc. But of course no one will, save very rarely, underestimate his good sense, and it is more comfortable to assign its deficiencies to the memory. This occurs not only in words but also in construction. If a man has incorrectly reproduced any matter, whether a false observation, or a deficient combination, or an unskilled interpretation of facts, he will not blame these things but will assign the fault to memory. If he is believed, absolutely incorrect conclusions may result.

Section 56. (e) Mnemotechnique.

Just a few words concerning mnemotechnique, mnemonic, and anamnestic. The discovery of some means of helping the memory has long been a human purpose. From Simonides of Chios, to the Sophist Hippias of Elis, experiments have been made in artificial development of the memory, and some have been remarkably successful. Since the middle ages a large group of people have done this. We still have the figures of the valid syllogisms in logic, like Barbara, etc. The rules for remembering in the Latin grammar, etc., may still be learned with advantage. The books of Kothe and others, have, in their day, created not a little discussion.

As a rule, modern psychology pays a little attention to memory devices. In a certain sense, nobody can avoid mnemonic, for whenever you tie a knot in your handkerchief, or stick your watch into your pocket upside down, you use a memory device. Again, whenever you want to bear anything in mind you reduce difficulties and bring some kind of order into what you are trying to retain.

Thus, some artificial grip on the object is applied by everybody, and the utility and reliability of this grip determines the trustworthiness of a man’s memory. This fact may be important for the criminal lawyer in two ways. On the one hand, it may help to clear up misunderstandings when false mnemonic has been applied. Thus, once somebody called an aniline dye, which is soluble in water and is called “nigrosin,” by the name “moorosin,” and asked for it under that name in the store. In order to aid his memory he had associated it with the word for black man = niger = negro = moor, and thus had substituted moor for nigro in the construction of the word he wanted. Again, somebody asked for the “Duke Salm” or the “Duke Schmier.” The request was due to the fact that in the Austrian dialect salve is pronounced like salm and the colloquial for “salm” is “schmier” (to wipe). Dr. Ernst Lohsing tells me that he was once informed that a Mr. Schnepfe had called on him, while, as a matter of fact the gentleman’s name was Wachtel. Such misunderstandings, produced by false mnemonic, may easily occur during the examination of witnesses. They are of profound significance. If once you suspect that false memory has been in play, you may arrive at the correct idea by using the proper synonyms and by considering similarly-pronounced words. If attention is paid to the determining conditions of the special case, success is almost inevitable.

The second way in which false mnemotechnique is important is that in which the technique was correct, but in which the key to the system has been lost, i.e., the witness has forgotten how he proceeded. Suppose, for example, that I need to recall the relation of the ages of three people to each other. Now, if I observe that M is the oldest, N the middle one, and O the youngest, I may suppose, in order to help my memory, that their births followed in the same order as their initials, M, N, O. Now suppose that at another time, in another case I observe the same relation but find the order of the initials reversed O, N, M. If now, in the face of the facts, I stop simply with this technique, I may later on substitute the two cases for each other. Hence, when a witness says anything which appears to have been difficult to remember, it is necessary to ask him how he was able to remember it. If he assigns some aid to memory as the reason, he must be required to explain it, and he must not be believed unless it is found reliable. If the witness in the instance above, for example, says, “I never make use of converse relations,” then his testimony will seem comparatively trustworthy. And it is not difficult to judge the degree of reliability of any aid to memory whatever.

Great liars are frequently characterized by their easy use of the most complicated mnemotechnique. They know how much they need it.

Topic 7. THE WILL.

Section 57.

Of course, we do not intend to discuss here either the “will” of the philosopher, or the “malice” or “ill-will” of criminal law, nor yet the “freedom of the will” of the moralist. We aim only to consider a few facts that may be of significance to the criminal lawyer. Hence, we intend by “will” only what is currently and popularly meant. I take will to be the inner effect of the more powerful impulses, while action is the external effect of those impulses. When Hartmann says that will is the transposition of the ideal into the real, he sounds foolish, but in one sense the definition is excellent. You need only understand by ideal that which does not yet exist, and by real that which is a fact and actual. For when I voluntarily compel myself to think about some subject, something has actually happened, but this event is not “real” in the ordinary sense of that word. We are to bear in mind, however, that Locke warned us against the contrast between intelligence and will, as real, spiritual essences, one of which gives orders and the other of which obeys. From this conception many fruitless controversies and confusions have arisen. In this regard, we criminalists must always remember how often the common work of will and intelligence opposes us in witnesses and still more so in defendants, causing us great difficulties. When the latter deny their crime with iron fortitude and conceal their guilt by rage, or when for months they act out most difficult parts with wonderful energy, we must grant that they exhibit aspects of the will which have not yet been studied. Indeed, we can make surprising observations of how effectively prisoners control the muscles of their faces, which are least controllable by the will. The influence the will may have on a witness’s power even to flush and grow pale is also more extensive than may be established scientifically. This can be learned from quite remote events. My son happens to have told me that at one time he found himself growing pale with cold, and as under the circumstance he was afraid of being accused of lacking courage to pursue his task, he tried with all his power to suppress his pallor, and succeeded perfectly. Since then, at court, I have seen a rising blush or beginning pallor suppressed completely; yet this is theoretically impossible.
